IMPROVEMENT IN PUMPS.

Thel Schedule referred to in these Illiettern` Patent and making part of the same.

To all to 'whom it may concern.'

Beit known that I, A. N. PaRKuUnsT, of Knox-` ville, iu the county of Knox, andwState' of Illinois, have invented a. new and usefulv Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to the accompanying drawings, making a part of'this specification. in which- Figure l is -a perspective view.

`Figure 2 is a. vertical section.

Figure 3 is a view, in detail, of collar.

Figure 4 is a view, in detail, of the clamp. Y

Like letters in the figures ot" the drawings indicate like parts.

bl y invention is intended as :tu improvement upon that `patented by me February 10.1863. I construct the stock or top A ofthe pump ot' a similar form and miterial asin that, the' cylinder or chamber B being separate, and made of stone-baked clay, glazed or "vitriticd in the interior, and having anges d d at the upper and lower ends thereof, by which itis united to the. pump-stockv above, and to a metallic collar, C, with iiange c below, which collar is driven on to the tubing 1),' the latter forming'the'npper termination of' the wooden tubing o1' pipe, by means of bolts f through the [langes 1l c.

Having thus given a general outline of the construction of' this pump, as improved, I will proceed with a detailed description oi it.

The chamber or cylinder B isof the same material and shape as before deseribed,its flanges d ll heilig pierced with a sutiicient number of holes to receive bolts c c and ff, uniting it with the stock A.

Around the base ofthe latter are placed two or more clamps 1),-with a claw, 7.', at` the upper end of each, which bite into the wood ot' the stock, and are further secured to the same by means ot' several screws.

Each of these. clamps terminate below, near the base ofthe stock, in horizontal projecting jaws fi'i, which receive the bolts c, by which the connection is made to the cylinder, through the perfm'ations in the ilauges thereof, as before described, rubber or other appropriate packing being placed between the joints ofthe stock and chamber.

To connect my tubing (of wood) with the chamber or earthenware cylinder, I construct a collar, G, ot' metal, ot' a bore about the sizeof' that ot' the cylinder, and having a tia-nge, c, which corresponds with and is bolted to the tiange :l ofthe former.

-I make the tube ofthe collar aboutfot'our inches deep, or deep enough Vto form a suticient hold, when driven on to the end of the wooden tubing, the bot` tom edge, on inside of collar, being tapered, so as to wedge itseli` tightly onto the wooden tubing, the top of the latter thrilling the valve-seat g, at or nearthe junction of the collar and chamber.

The tianges e of' the collar are united to that of the A chamber B by bolts f and nuts, with the rusual packing at the joint.

The lower edge of the tube of collar is strength- Aened, by means of an enlargement ofthe metal, iu

the shape ot' an annnlet, on. on its outside.

The piston or bucket is of' any simple construction, and the same as described in my original patent.

The improvement sought to be accomplished by this construction of pump is, first, the attaching ot' a metal collar, C, with flange, for connections to the upper end ofthe wooden piping, in order to furnish a more ready aml convenient place of connection or division ot' the pump at the insertion or pointI ot" location ot' the valve, an important desidera-tum in pumps of all kinds, by which tacility oi' examination of the valve is presented.

Secondly,rthe doingr away wit-h the weight and eX- pense ot' heavy cast-iron tlange, by which the pump and tubing was hung to the platforn'i ofthe cistern or well, this mode ot construction enabling the pump to rest on the bottom ot' well or cistern, and steadied by the square part ofthe stock, so that farmers, and others unacquainted` with these articles, may take them apart, and examine the valves, and adjust any damage, with much greater facility than pumps of Y any other construction at these points.

Thirdly, the clamps b b, which supersede the com bined long clamp-bolt used in my tirst patent, above mentioned, and forming a stronger, simpler, and cheaper coupling of the stock to the chamber.

Fourthlyfthis construction of pump is much more economical and simpler, both in placing in position, as in removing it., or repairing it, and is also much cheaper to make, saving as much as two dollars in the construction ot' each pump.

Claim.

Having thus fully described my invention,

NVhat l Yclaim therein as new, and desire to secure by Letters Patent, is-

The baked-clay chamber B, having its upper end united to the stock'A' by clamps b, provided with open jaws t i, to Vreceive thc` boits, and its lower end, or base,` united lto the collar C, having its lower interior edge tapering, and provided on itsouter edge with the aunulet m, when the said colla-r 'is arranged and driven on the stock D, so that the, ina-in connection of the pump may be made at the point of location of valve g thereon, substantially in theV manner and for the purpose as shown .and described.

In testimony that I claim the foregoing, I have hereunto set my hand, this 12th day ot' May, 1869. A. N. PARKHURST.
